Find n smallest values in an n dims array

[marianoarnaiz]

@mkitti

function arg_n_smallest_values(A::AbstractArray{T,N}, n::Integer) where {T,N}
           perm = sortperm(vec(A))
           ci = CartesianIndices(A)
           return ci[perm[1:n]]
       end

Thanks guys. This should be included somewhere in Julia
